PIPE

' Filed Oct. 24, 1933 WITNESSES.- INVENTOR HIS A'TTORNEY Patented May 12, 1936 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to pipes, and has for an object to provide a pipe having improved means for providing reversely directed flow of smoke within the stem.

A further object of the invention is to provide a pipe having a tube inserted into the stem, producing an annular space, and with a mouthpiece having a tube inserted into the first mentioned tube for directing the flow of smoke reversely 10 within the stem.

The invention, therefore, comprises a pipe embodying a bowl, a stem and a mouthpiece, the stem being bored to receive a tube therein and the mouthpiece being provided with a. conduit 15 insertable into the tube, with means for making relatively smoke and air-tight connection between the tube and the mouthpiece, with the exception of a channel provided for the purpose of admitting smoke from the annular space about 20 the tube into the interior of the tube, and from the interior of the tube into the conduit and therefrom into the mouthpiece.

The drawing illustrates an embodiment of the invention and the views therein are as follows:

Figure 1 is a view of the pipe in longitudinal section upon a plane substantially axial of the bowl,

Figure 2 is a view in elevation of the mouthpiece and its associated parts,

Figure 3 is a transverse sectional view taken on line 33 of Figure 1,

Figure 4 is a transverse sectional view taken on line 44 of Figure 1, and

Figure 5 is a perspective view of the tube, it being understood that all of Figures 3, 4 and 5 are on a scale greatly enlarged relative to Figures 1 and 2.

Like characters of reference indicate corresponding parts throughout the several views.

The pipe as an entirety comprises a bowl H), a stem H and mouthpiece l2. These may be of any usual and ordinary shape, to meet the demand of the trade, and the exact shape as shown in the drawing is only illustrative, and no limita- 5 tion upon the invention.

The stem I I is bored to receive the tube l3 and to provide an annular space M about said tube. One end of the tube is closed, as at l 5, and the opposite end is provided with a plug it hav- 5g ing a shoulder ll, which is of substantially the same diameter as the tube, and both the shoulder I! and the plug [6 are provided with a continuous groove IS. The plug l6 carries the conduit 19 which extends within the tube I 3 and adjacent 5 to the closed end 15 thereof.

Beyond the shoulder I! the plug is continued by a constricted neck portion l9 which is attached to the part 20 of the mouthpiece [2 which is inserted within the bore of the stem. Preferably, the bore of the stem will be cylindrical throughout its extent, and will communicate by means of a passage 21 with the bowl ID.

The arrangement is such that a chamber 22 is provided between the end of the tube I3 and the end of the bore, and a corresponding chamber 23 is provided by the constricted section l9 attached to the mouthpiece.

In use, smoke from the bowl I0 will pass through the vertical passageway 21 into the chamber 22 and from there through the annular space intervening between the tube l3 and the inner wall of the bore of the stem. The smoke will then reach the chamber 23 and will pass from this chamber 23 through the groove l8 into the interior of the tube I3, and the length of the tube l3 and enter the end of the conduit l9, passing through said conduit, through the plug l6 and constricted neck [9 into and through the mouthpiece [2.

It is intended that the tube I3 shall fit upon the plug so tightly that when the mouthpiece is removed from the stem by withdrawing the constricted portion 20, the tube I? will be removed therewith. After this removal the plug l6 and conduit l9 may be removed from the tube l3, whereupon the mouthpiece, with its associated parts, will be as shown at Figure 2, are accessible for cleaning; likewise the tube l3 will also be accessible for cleaning as well as the bore of the stem and the chamber 22.

By the construction and arrangement outlined, a pipe is provided with a considerably augmented conduit for cooling the smoke and at the same time the chamber 22 is provided for receiving moisture resultant from the combustion of the tobacco in the bowl l0, and moisture from the mouth of the user will pass through the conduit 99 into the tube l3.

The moisture from the two sources, therefore, will not commingle and the whole structure may be readily and conveniently cleaned when fouled.

Of course, the pipe herein illustrated may be modified and changed in various ways without departing from the invention herein set forth and hereafter claimed.

I claim:

A pipe comprising a. stem, a mouthpiece inserted by a sliding fit into the stem, a cylindrical plug fixed to the mouthpiece, a cylindrical tube carried by the plug, said plug having a shoulder spaced from the stem and the mouthpiece and having a longitudinal groove and a cylindrical closed end imperforate sleeve fitted onto the plug and abutting the shoulder, said sleeve being spaced from the walls of the stern throughout its entire length and the tube within spaced from the sleeve and all removable with the mouthpiece, said sleeve being removable from the tube and p 112'.
